    Notizen: Summary The pharmacokinetics of a single i. v. dose of dlbisoprolol 0.16 mg·kg−1 ideal body weight has been studied in 8 obese women (mean weight 91 kg; 161% of ideal body weight) and 8 non-obese women (51 kg; 94% of ideal body weight). Compared to the controls, the obese subjects showed an increase in the total apparent volume of distribution (Vz) (182 vs 135 1) and a decrease in Vz per kg body weight (2 vs 2.7 l·kg−1). There was a negative correlation between Vz l·kg−1 and the percentage of ideal body weight (r=−0.672). Total body clearance was increased, but t1/2 and renal clearance was unchanged. It is concluded that tissue diffusion of bisoprolol in obese subjects is limited, despite its lipophilicity, possibly because of alteration in the blood flow to adipose tissue produced by bisoprolol.

    Notizen: Summary The pharmacokinetics of d-sotalol has been studied in six healthy volunteers given single doses of 0.25, 0.50, 1, 2 mg·kg−1 i.v. and one 100 mg oral dose in comparison with the kinetics of 1 mg·kg−1 i.v. of dlsotalol. There was no significant difference in the disposition of the d-enantiomer and the racemate. The terminal half-life averaged 7.2 h, and the kinetics was linear, with a mean total clearance of 0.13 l·h−1·kg−1. Renal clearance of d-sotalol represented 56 to 77% of total clearance. The absolute systemic availability of oral d-sotalol was close to 100% and the elimination half-life of the oral-d-enantiomer was similar to that of the i.v. form (7.5 h).
